Why Most Mattresses Sleep HOT
(Except this one)


Sleeping hot

Chances are it’s not you, it’s your mattress.

Most mattresses don’t breathe. Memory foam, latex, even foam with “cooling” gel beads are hot because there is no place for air to flow.

These materials are either completely solid or have very small airways that allow for little ventilation.

But not all mattresses sleep like that.

Best color ever
Purple is officially the best color ever, just because of this mattress. Me and my boyfriend have constant back pain from sleeping, and he overheats too. No more back pain and cool sleeping for us now. Love love love this mattress!!!

Goldilocks cool

50 days and still loving the Purple Bed
I have had my bed for close to 50 days and I have to say I have never slept so well in my life. I wake up feeling refreshed and all my aches gone. One other thing that has to be pointed out, this bed does not get hot like other foam mattresses. In fact, it stays at a perfect temperature in my opinion, not too hot – not too cold…but just right. 5 stars for this bed!

How it works

First, we take Hyper-Elastic Polymer™—an ultra-stretchy, non-toxic, hypoallergenic, lots-of-hyphens
kind of material—and we put it on top of high-quality foam. We organize
this material in a 2-inches-tall by 1-inch-wide grid.


  • For deep sleep, you want less stimuli. If your mattress is too hot, it wakes you up. If it’s too cold, it wakes you up.
  • What you really want is your mattress to be temperature neutral—and if it aligns your spine at the same time, you have a recipe for incredible sleep.
  • Purple is crafted in a grid formation that helps it breathe. Instead of sleeping directly on foam, like you do with most mattresses, Purple elevates your body above the foam so air can flow freely.

It’s not just temperature! You also need your spine aligned

The walls that make up Purple’s Smart-Comfort Grid™ relax underneath pressure points while pulling to support areas like the lower back. This balances weight distribution and keeps the entire body in correct alignment.

Frequently Asked Questions

  • What Is a Cooling Mattress?

    Great question. The term “cooling mattress” can be used to describe several different mattress types that help you sleep cool. These mattresses can actively cool your body. They typically feature special materials or textiles within their cover or top comfort layer. These mattresses are great for hot sleepers because they actively work to lower and regulate your core body temperature for maximum comfort and the best night’s sleep.

    Cooling mattresses often use air circulation to keep your bed from trapping your body heat and raising your core temperature – which helps you sleep cool. These types of mattresses may feature coils and breathable foam instead of a gel-infused memory foam layer. The ultimate goal is to dissipate heat for the best temperature regulation.

  • What is the Best Mattress for Hot Sleepers?

    It’s not easy finding mattresses on the market that can keep heat and sweat away from your body while you sleep. Of course, we believe the best mattress for hot sleepers is a Purple® Mattress, thanks to the unique cooling properties of the patented Purple Grid — and we invite you to judge for yourself. With Purple, you can choose from several different mattress models, and you won’t overheat in any of them. We promise.

    The Purple® Mattresses offer unparalleled comfort and airflow, no matter your sleeping preferences. Back sleepers, side sleepers, and stomach sleepers can all stay cool and comfortable. The Purple® Mattresses offer the absolute best combination of air circulation, pressure relief, firmness, comfort, and responsiveness. You simply won’t find anything else like it on the market for a great night’s sleep.

    Latex is known for sleeping cool, but can be very expensive and most varieties are known to break down quickly (Talalay latex, which is in our Purple® Harmony Pillow, is extremely durable and cool). When it comes to sleeping hot, most hot sleepers complain that memory foam traps heat worse than other types of mattresses. Even gel memory foam heats up — and because it’s heat-activated, you don’t get consistent comfort throughout the night. Other than a Purple, a good mattress for hot sleepers will likely be a traditional innerspring mattress, which is inherently less dense than memory foam or gel. Traditional innerspring mattresses have their own pros and cons, but they do allow for better air circulation. The newer coil technology, individual pocketed coils, are great for personalized support and airflow, especially when paired with a Purple Grid. If you know you have a tendency to sleep hot, it’s a good idea to steer clear of dense foam and give Purple a try.

  • How Can I Sleep Cooler at Night?

    Sleeping cooler isn’t just a nice idea, it’s one of the key ingredients of a great night’s sleep. Lowering your core body temperature sends a signal to your brain that it’s time to shut down and get some rest. Before bedtime, lower the thermostat so you can reach your ideal sleeping temperature. Many experts recommend temperatures between 60 and 67 degrees for optimal sleep comfort.

    Make sure you’re getting into a bed made up with light, breathable sheets – think bamboo sheets. You can also invest in a cooling pillow – or at least make sure your pillow is plenty breathable to allow for sufficient air circulation. This can help dissipate some of the heat your body generates and keep it away from your bed. Many newer pillows on the market are designed to provide healthy air circulation and comfort without sacrificing any appropriate neck support. Hint: Try the Purple Harmony Pillow. We’re pretty sure it’s the best pillow for hot sleepers. And if you don’t agree with us after sleeping on it, we’ve got a 100-night sleep trial so you can try the Purple® Pillow risk-free.

    You may want to use a fan to give your bedroom extra airflow. In fact, you can get creative with fan placement to make the most of your room temperature. For example, try creating a cross breeze by using multiple fans, and even opening windows, depending on the outdoor temperature. You might want to experiment with the placement of a few fans to see which gives you the best comfort. A nice, cool shower right before bed can also help lower your body temperature. Instead of fully drying off, let some water evaporate from your skin, which will create a nice, cooling effect.

  • Why Do I Get So Hot at Night When I Sleep?

    As we sleep, our bodies give off heat as our core temperature lowers – this lowering of temperature makes it possible for us to sleep more deeply, but the heat from our bodies is often trapped by our mattress and bedding (such as a plastic mattress protector or quilted covers) around us. If you’re someone who tends to sleep cold, this phenomenon can help you feel cozy – but if your temperature naturally runs a little higher, this body heat can make you feel like you’re trapped in a sauna.

    Typically, the heavier you are, the hotter you sleep. This is because a larger body mass covers a larger surface area of the bed. Heavier people tend to require more support and pressure relief, as well, so the best cooling mattress is likely to be a hybrid mattress that can provide plenty of support and comfort while remaining breathable.

    Many of us simply wear the wrong clothing at night. Try to keep pajamas and other sleepwear light and breathable so that your clothing isn’t trapping additional heat. Most sweating at night is completely normal. It’s commonly caused by the sleeping environment being too warm, but there are times when excessive night sweats are caused by a medical condition. Certain infections, hormone disorders, hot flashes, and even anxiety can cause you to feel hot. If nighttime sweats are interrupting your sleep on a regular basis, it may be time to talk with your doctor.

  • What Features Should I Look for in a Cool Mattress?

    When it comes to choosing the best mattress for hot sleepers, there are several important comfort features to consider. First, the mattress needs to be made from the right kind of material. You need a high-quality mattress that features an innovative and breathable material. You should also consider whether you’re more interested in an active or passive cooling mattress. While an active cooling mattress can incorporate a noisy fan or water pump, a passive cooling mattress is naturally more breathable and allows for sufficient air to flow around your body. Or it may be made of an innovative fabric or foam that helps draw heat away from your body.

    And at the end of the day, a cooling mattress is still a mattress. In addition to helping you sleep cool, your mattress needs to provide the right level of firmness, pressure relief, support, and comfort you need for a good night’s sleep. A good mattress review can be extremely helpful, so do some research and check out online mattress reviews for info about how a certain brand performs for hot sleepers.

  • What Materials Make the Best Cooling Mattress?

    You can find cooling mattresses made of a wide variety of materials. Often, the best ones are hybrid models that incorporate several different materials along with various types of technology. For example, Purple combines pocket coils with high-density foam and the Purple Grid to provide a good night’s sleep. Be careful with models featuring cooling gel, latex, or a gel memory foam layer. Many mattresses that feel cool can heat up significantly during the night.

    Purple Grid – Purple is in a class of its own, thanks to its patented Hyper-Elastic Polymer as its top layer. This scientific material allows air to flow freely, so it helps with temperature regulation without actively cooling hot sleepers. You won’t feel like you’re sleeping on a glacier — you’ll feel just right.

    Pocketed coils – Like innerspring mattresses, mattresses with individual coils provide excellent airflow. A Pocketed coil mattress has many benefits when compared to traditional innerspring mattresses. Pocketed coils are great for sleeping with a partner since they are quiet, have less motion transfer, and provide superior responsivity.

    Innersprings – Loaded with springs, a traditional mattress provides ample air circulation which can help keep you cool while you sleep. The more springs your bed has, the better usually the airflow. Innerspring mattresses can be noisy, and they tend to transfer motion, but these annoyances may be worth it if sleeping cool is your top priority.

    Foams – Be careful here. You might find a foam mattress with added elements, like copper, for example, that can help them repel heat, but many types of foam — particularly memory foam — are known for trapping heat and making you sleep even hotter. If you go for some type of cooling foam mattress, make sure you have a sleep trial and the option to return the mattress if it starts to roast you. Gel-infused memory foam can help a little — but it’s still a memory foam layer. Cooling gel starts off feeling cool but will heat up during the night just regular memory foam. Poly foam is typically breathable, but it needs to be paired with a cooling material like the Purple Grid or you can wake up covered in sweat.

  • How Do You Cool Down a Hot Sleeper?

    If you wake up from overheating, there are several things you can do to cool down, increase your comfort level and get back to getting a good night’s sleep. Let’s look at a few.

    Sleep like an Egyptian – legend has it that this method of cooling down goes back to ancient Egypt when hot summer nights made it tough to sleep. You can take a clean, dry cloth, spritz it with cold water and place it under your neck. And just a spritz is enough – you don’t have to lie on top of a soaking wet cloth to get the cooling effect and amazing sleeping temperature regulation.

    Turn on the fan – try to position a small, tabletop fan on your bedside table. You can position it to blow directly on you while you sleep, which can help dissipate heat to keep you feeling cooler and more comfortable throughout the night.

    Grab an ice pack from the freezer – Cool packs are great for sore muscles, but they can also help you cool down at bedtime. When you’re running hot during the night, you can grab a frozen ice pack and lay it on your forehead for 10-15 minutes. You may want to use a cloth or towel if it feels too cold on your skin. You can chill yourself to sleep in no time!
